Need some advice about the drone I am experiencing. Several months ago I installed fabspeed headers and Brian's (Rarlyl8) dual out exhaust. I love the sound and noticed a huge improvement in performance but the drone is taking a toll on me. The drone seems to have increased gradually over the last several months. I did PM Brian a while back and he told me I should not be experiencing drone with his exhaust. So not sure what to do at this point. Any advice on the easiest way to trouble shoot this to find out if it is my headers vs. muffler? Maybe I am getting too old. Does anyone else experience drone with their exhaust setup? Anyone else experiencing drone with Brian's exhaust. BTW my drone is from about 2K to 2800rpm.
